View Full Version : Iridium Spark Plugs

I'm buying some NGK Iridium spark plugs.

How do Iridium Spark Plugs compare to the usual kind? I got some Denso Platinums in my S14 at the moment. Any performance gains, or is it just a waste? I hear its good for a turbo or something but how about for a NA app? All I'm running is an intake at the moment.

You have beter spark plugs in your car now...
You should stick with platinums in a bit of colder range. I would say step down to an 8 (from 7).

Denso is not bad, but there are much better plugs.
If you want a set of good racong plugs, we have NGK racing plugs for the SR20DET with mild to moderate upgrades and boost up.

Let me know
